For example the remote transmitter may be measuring temperature and converting it to a standard mA signal In such a loop though the input module cannot determine the state of the loop on the far side of the transmitter However the remote transmitter may be capable of diagnosing a problem in the remote loop and signal the input module local loop with a preprogrammed out of range high or low value The Remote Fault Alarm allows the 1797 IE8 and IE8NF modules to work with transmitters like the one just described You must use the Remote Transmitter Error Up or Down feature see page 2 3 to configure your application for Remote Fault notification For example you must determine if you want a remote fault to cause high out of range values or low out of range values to be returned to the controller IMPORTANT Once the alarm is issued it remains active as long as the input signal value remains above the programmed value Using Remote Fault Alarm to Determine High High or Low Low Alarm Levels If you do not have a remote transmitter in your loop this alarm can also be used to program a high high or low low alarm level between the levels which actuate the overrange or underrange alarms and the high or low local fault alarms IMPORTANT When establishing high high or low low alarms you can only select one side high or low You must use the Remote Transmitter Error Up or Down feature in conjunction with this alarm Publication 1797 6
